8 Claims.

Another important object of the invention resides in the provision of a concrete slab adapted for disposition within a wall between a pair of spaced studs, wherein the slab is specially constructed to coact with a water closet bowl, the latter being also formed of concrete, and wherein the slab is formed with a water tank, there being means provided for supplying water to the tank from a suitable source of supply and for discharging the water from the tank into the interior of the bowl.

A still further object is to provide Va water closet construction embodying a novel waste conduit having slidable and detachable engagement with the bottom of the water closet bowl, and which waste conduit is also formed of concrete material.

A still further and important object is to provide a construction of the above mentioned character wherein the use of the conventional metal pipes and ttings as are ordinarily associated with a water closet is eliminated, thereby rendering the device inexpensive and capable of quick and easy assembly.

Other objects and advantages of the present invention will become apparent during the course of the following description, when taken in connection with the accompanying drawing.

In the drawing forming a part of this specification and in which like reference characters designate corresponding parts throughout the several views:

Figure 1 is a vertical sectional view taken approximately on the line I-I of Figure 2;

Figure 2 is a vertical sectional view taken approximately on the line 2-2 of Figure 1, looking in the direction of the arrows;

Figure 3 is a horizontal section taken approximately on the line 3-3 of Figure 1, looking downwardly;

Figure 4 is a similar section taken approximately on the line 4-4 of Figure 1, also looking downwardly; y

Figure 5 is a horizontal section taken approximately on the line 5-5 of Figure 1, and

Figure 6 is a detailed view showing one of the conduits provided with a metal pipe liner, as a modification.

In the drawing, wherein there is shown a preferred embodiment of my invention, the numeral I designates generally a wall of a building yand a pair of spaced vertical studs 2 form a space 3 therebetween, the purpose o f which will be presently described. The oor is designated by theA numeral Il.

Fitted within the space or recess 3 between the spaced studs 2 is the elongated concrete slab 5. This slab is formed with a substantially rectangular shaped pocket 6 in the front face of the lower portion thereof. Also formed in the front face of the lower portion of the concrete slab on opposite sides of the central pocket 6 are the side compartments 'I and 8. The latter may be used for the reception of various articles, such as toilet paper, syringes, etc.

Formed integrally with the upper portion of `the concrete slab 5 and projecting outwardlyv from the front face thereof is the water tank 9.

A removable cover I0 is provided for thev open top of the water tank. A discharge conduit `-I I extends from the bottom of the water tank 9 to -the top ofthe pocket 6. A gravity seated valve I2 normally rests on the' upper end of the conduit I I within the tank 9. The valve stem associated with the valve I2 is designated by the' numeral I3 and is slidable within a suitable guide I4 within the tank. An actuating cable I5 is connected to the upper end of the valve stem I3 and is disposed through a suitable guide I'I that depends from the top portion of the water tank and the outer end of this cable extends through anv A valve 22 is associated with the water supply line 2l and a foot operated treadle 23 that extends upwardly through the floor, controls the opening and closing of the valve 22, in the man ner also to be hereinafter more fully described.

The upper portion of the concrete slab 5 in the rear of the water tank 9 is formed with a by-pass conduit 24, the upper endk of thisby-pass conduit having communication with the top portion of the water tank 9, while the lower end of this by-pass conduit communicates with the discharge conduit II.

It is to be understood that the various conduits formed in the concrete slab 5 are produced by the usual plastic molding methods and suitable cores are employed for forming the various conduits, it being understood that these cores are removed after the plastic material has set.`

Also forming a salient part of the present invention is the concrete water closet bowl 25. The rear body portion 26 of the water closet bowl is substantially rectangular in cross section andis adapted to t snugly within the pocket Yi5. provided therefor in the lower portion of the concrete slab 5, in the manner as clearly shown in the drawing. The receptacle portion of the bowl is denoted by the numeral 21 and water is supplied thereto from the rim portion 28 in the conventional manner. The top of the water closetbowl may be either finished off to form a seat portion or if desired, a separate seat may be mounted thereon.

A conduit 29 is formed in the top of the body The water closet bowl is-provided with the.A

conventional trap 3S that has communication with the receptacle portion 21 and the discharge conduit 3| that is formed in the body portion of the bowl.

communication with the horizontally extending waste conduit 32, through the opening 33..

This waste conduit 32 is also formed of concrete material and is disposed horizontally beneath the floor 4. The upper portion oi this conduit is formed with laterally extending flanges 34 at the sides thereof for slidable engagement with the channeled portions `35 that project downwardly from the face of the bowl and body portion thereof, in the manner as is more clearly illustrated in Figure 2. K A I The concrete waste `conduitA 32 is vfurther formed with the vent 3S and the latter has communication with the interior of the conduit, as at 31. The inner end of the conduit 321s closed, while the other end is adapted for connection with the conventional waste or sewage pipe not shown.

The lower end of the discharge con duit 3| extends to the base of the bowl and has l By pulling on the cable I5, the valve I2 will be unseated, thus permitting the water to be discharged from the tank 9 into the conduits I I and 29 and iinally delivered to the receptacle 21 of the water closet bowl 25 and the contents of the receptacle 21 are ultimately discharged into the waste conduit 32 through the discharge conduit 3l and opening 33.

It will thus be seen from the foregoing description that I have provided a water closet construction that does not require the use of any critical metals and due to its simplicity, the same may be molded from concrete or any other suitable plastic material at a very low cost. Such a structure Vis particularly desirable in the installation of water closets in low cost buildings and apartments, as well as portable knock-down houses.

A structure of the above-mentioned character will, at-all times, be positive and eiiicient in its operation and canvbe very easily assembled;

If necessary, the conduits formed in the-cementv slab and water closet bowl may be lined with lead pipes, such as is indicated at 38 in Figure 6, although it is preferred not to use any metal liners in the conduits.
